No. 10/290,183, filed Nov. 8, 2002, now U.S. Pat. No. 6,662,959. The contents of each of the aforementioned applications and patent are hereby incorporated herein by reference in their entirety. Priority to the aforementioned applications is hereby expressly claimed in accordance with 35 U.S.C. §120 and any other applicable statutes.

FIELD OF THE INVENTION

The present invention is directed to the conversion of a beverage bottle into a stemmed drinking glass by the consumer.

BACKGROUND

Single serving wine bottles are known in the art. These are essentially smaller versions of standard 750 ml. wine bottles, and generally have a metal cap. Once purchased, the cap is removed and the contents are poured into a separate glass for consumption. In situations when a glass is not available, one could drink the wine directly from the bottle.

The instant invention overcomes this problem of requiring a separate glass to be employed with a single serving wine bottle by making the single serving wine bottle convertible into a wine glass. The instant invention is such that if all the wine is not consumed, a cap can be replaced on the bottle until it is so desired to be consumed. A wine bottle which converts easily into a wine glass would find utility in the airline industry, the alcoholic beverage industry, bars, hotels, clubs or anywhere wine is served. Such a device may also be employed with wine coolers or other alcoholic beverages. In addition, the novelty of such a new and convertible device may be of interest to the bottling industry in general, where new ways to package beverages often increases their sales.

SUMMARY OF THE INVENTION

A wine bottle convertible to a wine glass permitting the consumption of the wine directly therefrom is provided. The wine bottle may be sized to house a single serving of wine. The convertible wine bottle comprises four main elements which are assembled and filled with wine in a bottling process. The wine bottle has basically four integrated components with ancillary structure. These four components are assembled and filled with wine at a bottling plant. Once bottled, the convertible wine bottle may be packaged in 4-, 6-, or 8-packs, as well as individually. The wine bottles would then be transported and sold. These four integrated components are manipulated by the consumer to transform the wine bottle into a wine glass with an appropriate portion of wine therein. Such a convertible bottle of wine would give users the pleasure of drinking their wine from a stemmed glass. Once completed, the structure may be reassembled and recycled.

The first element (stem and base) is the stem and base of the wine glass. The first element may be manufactured from plastic. The base includes a centrally disposed stem depending vertically therefrom. The base is designed to support the glass when the bottle is converted. The top portion of the stem may include a threaded socket or smooth socket. The base also is designed to be snap-fit or otherwise attached to the bottle prior to conversion to the wine glass.

The second element is a bottom closure which includes a generally cylindrical sidewall which has an interior side and an exterior side. The second element includes a centrally disposed parabolic portion which resides in the interior of the cylindrical sidewall. The interior cylinder sidewall includes threading to securely attach the second element to the third element. The parabolic portion forms a bowl on the exterior side and a displacement element on the interior side. The stem of the first element would reside within the bowl of the parabolic portion in the wine bottle configuration. The second element is manufactured from plastic or metal. It essentially forms a closure which is air and fluid tight with the third element forming a fluid reservoir which may be accessed through an aperture on the opposite side of the third element (the neck).

The third element comprises the main body of the bottle and has a generally cylindrical sidewall which also has an interior and an exterior side. The cylindrical sidewall has a top portion and a bottom portion along a vertical axis of said cylindrical sidewall. The top portion of the cylindrical sidewall has a neck with an opening. The top portion of the cylindrical sidewall may taper to form the neck. The bottom of the cylindrical sidewall forms a large opening which comprises the lip of the glass from which a user drinks when the bottle is converted to a wine glass. The exterior side of the bottom portion of the cylindrical sidewall has threads. These threads securely engage with the second element's interior sidewall threading. The neck is the portion of the bottle to which a cap will be affixed. Thus, the external portion of the neck is threaded and designed to receive a cap thereon. It is proposed that the third element be manufactured from glass, plastic or other material.

The third element may also have a lip extending radially outward from cylindrical sidewall at or near the bottom end of the cylindrical sidewall. The lip provides a seal between the second element and the third element, in addition to the seal provided by the engagement of the respective threads. To accommodate the lip, the diameter of the interior side of the cylindrical wall of the second element may be increased, also increasing the diameter of the threads on the interior side. In order to mate with the threads, the cylindrical sidewall of the third element in the area of the threads may thickened to form a band so that the threads can still mate with the threads in the second element's interior sidewall. The thickened band also makes the cylindrical sidewall of the third element stronger and more rigid in the area of the threads. In this way, the seal provided by the threads can withstand greater forces caused by squeezing the bottle or other handling of the bottle.

In another innovative aspect of the present invention, the threads on the cylindrical sidewall of the third element may be disposed on the interior side of the sidewall, instead of the exterior side as described above. In order to seal effectively to the threads of the interior side of the sidewall, the centrally disposed portion of the second element is cylindrical instead of parabolic. Threads are provided on the exterior side of this centrally disposed cylindrical portion which mate with the threads on the interior side of the sidewall. This configuration provides several advantages, such as eliminating the threads on the exterior side of the sidewall in the area where a user's mouth contacts the sidewall when drinking from the glass. Moreover, the seal between the second element and the third element seals the beverage in the bottle at the mating threads before the beverage reaches the interface between the edge of the sidewall at the large opening of the third element and the interior side of the bottom of the second element. Thus, there is no need to provide a fluid tight seal at the interface. This also eliminates the need for using a lip extending radially outward from cylindrical sidewall at or near the bottom end of the cylindrical sidewall as described above.

The combination of the second element and the third element forms the reservoir which will be filled with wine. The interior side of the parabolic portion of the second side forms a displacement area which alters the amount of fluid which may be placed in the reservoir (in comparison to a second element with no parabolic portion). This displacement area would also effect the amount of air present. Air tends to oxidize wine therefore it should be minimized. Wine has been bottled for years and the amount of air present in the bottling process has been established to maximize flavor and shelf-life.

In another aspect of the present invention, the third element may be formed by several different methods. In a first method, the third element may be molded (such as injection molding) in essentially its final form. Accordingly, the cylindrical sidewall, the threads on the neck and the threads on the bottom portion of the cylindrical sidewall are molded in their final form. In addition, the neck and bottom of the third element have openings provided by the molding process.

Alternatively, the third element may be produced in a two-step process utilizing a preform and a blow-molding process. The preform may have various innovative configurations, including being open and clamped at the small neck opening of the third element during the blow-molding process, being open and clamped at the large opening of the third element, or open at both ends and clamped at one end and sealed at the other end of the third element.

For example, the preform may comprise a tubular piece having a diameter which is smaller than the finished diameter of the cylindrical sidewall of the third element. The top part of the tubular piece is open and forms the neck of the third element. The threads on the neck may or may not be formed on the preform. The bottom of the tubular piece is closed. The threads on the exterior side of the bottom portion may be formed on the preform but are preferably formed during the blow-molding process. The preform is typically produced by injection molding but may be produced by any suitable method. To form the finished third element, the preform is placed in a blow-molding machine having a mold tool in the shape of the final form of the third element. The preform is clamped at the top part of the tubular piece. Pressurized gas is injected into the preform which forces the material of the preform against the mold tool which shapes the preform into the shape of the mold tool. The threads on the exterior side of the bottom portion of the cylindrical sidewall are formed during the blow-molding process (if the threads were not included in the preform). The bottom end of the cylindrical portion is then trimmed to form the large opening.

In another blow-molding process, the third element may be produced using a preform with a tubular top portion having the same diameter as the bottom portion of the cylindrical sidewall and the large opening. The threads on the exterior of the side of the bottom portion of the sidewall are preferably formed on the preform but may also be formed during the blow-molding process. The large diameter of the preform tapers down to a narrower tubular bottom portion having a closed end which will comprise the neck of the third element after the blow-molding process. Again, the preform may be fabricated by injection molding or other suitable process. The finished third element is produced by placing the preform in a blow-molding machine having a mold tool in the shape of the final form of the third element. The preform is clamped at the tubular top portion of the preform. Pressurized gas is injected into the preform thereby reshaping the preform into the shape of the mold tool. The threads on the neck of the third element are formed during the blow-molding process (if the threads were not included in the preform). The tip of the closed neck end is then trimmed to form the opening in the neck.

In yet another blow-molding method, the preform for the third element may comprise a tubular piece which is open on both ends. The tubular piece is the same length as the interior of the blow-mold tool and at least a portion of the tubular piece has a smaller diameter than the finished cylindrical sidewall of the third element. The threads on the neck and on the exterior of the bottom portion of the sidewall may be formed in the preform or during the blow-mold process. During the blow-mold process, one open end of the preform is clamped at the pressurized gas source and the other open end of the preform is sealingly pressed or clamped against the end of the interior of the mold. Pressurized gas is injected into the preform thereby reshaping the preform into the shape of the mold tool. The advantage of this particular “two open end” process is that there is no trimming required as in the two blow-molding processes described above. The trimming processes present a risk of deforming the shape of the openings which could produce a poor fit between the bottom cover and the threaded portion of the third element or the cap (described below) and the neck of the third element.

The fourth element (cap) is a cap which is secured to the neck of the third element. The wine is delivered to the bottle (which is formed by the combination of the second and third element) through the aperture in the top of the neck. Once filled, the fourth element is secured thereto. The cap is designed to be manufactured from metal or plastic and will seal the bottle to prevent air or fluid from passing either direction.

The above brief description sets forth rather broadly the more important features of the present invention in order that the detailed description thereof that follows may be better understood, and in order that the present contributions to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, a wine bottle convertible to a wine glass embodying the principles and concepts of the present invention will be described. In the case of a bottle being converted into a glass, it is to be understood that this glass is a drinking glass and may be comprised of material other than glass, such as plastic.

Turning initially to FIG. 1, the unassembled wine bottle 10 which is convertible into a wine glass is shown. FIG. 1 shows the components employed. Element 1 shows the base 12 with a centrally disposed stem 14 depending therefrom. The bottom portion 15 of the stem 14 includes a hollow aperture 16 with an interior which may be smooth or threaded. Other means may be incorporated to increase the frictional holding capacity of the hollow aperture. Such means may include mechanisms which would increase the co-efficient of friction. The base 12 has a perimeter 18. A lip portion 20 depends around the perimeter 18 of the base 12.

Element 2 includes a generally cylindrical sidewall 22 which has an exterior side 24 and an interior side 26. Element 2 includes a centrally disposed parabolic portion 28 or depression which resides in the interior of the cylindrical sidewall 22. It describes a parabolic opening 30 which is surrounded on the top 32 by a ring 34. The parabolic portion 28 is thin and approximates the thickness of the sidewall 22. On the interior side 26 of the cylindrical sidewall 22 is a first set of threads 36. The parabolic portion 28 may also be described as a depression. The depression may assume other shapes other than the parabolic portion 28 which is shown in the figures. The interior area of element 2 is best seen in FIG. 10.

Element 1 fits into element 2. The stem 14 resides in the parabolic opening 30 and the lip portion 20 snap fits about the ring 34 on the top 32 of the second element. Tamper resistant or evident devices may be employed.

Element 3 also has a generally cylindrical sidewall 38 with a top portion 40 and a bottom portion 42 along a vertical axis of said cylindrical sidewall 38. The top of element 3 shows the sidewall 38 forming a circular opening 37. Circular opening 37 is surrounded by lip 35. Lip 35 would mate with the consumer's mouth when drinking the wine. Element 3 also includes an interior side 44 and an exterior side 46. A second set of threads 48 are located on the exterior side 46 of the cylindrical sidewall 38 of element 3. The second set of threads 48 are generally located above the midpoint (MP) between the top portion 40 and the bottom portion 42. Below the midpoint (MP) the cylindrical sidewall 38 tapers near the bottom portion 42 to a central neck 50 as shown. Central neck 50 includes an opening 52 to the interior side 44 of element 3. The exterior portion 54 of the central neck 50 includes a third set of threads 56.

Element 2 matingly interengages with element 3. The parabolic portion 28 fits into the circular opening 37 and the first set of threads 36 are mated with and rotated about the second set of threads 48 forming an air and fluid tight seal. Element 3 has a first volume which is reduced proportionally to the amount of the parabolic portion which fits into the interior.

Element 4 is a cap 58. Cap 58 includes a fourth set of threads 60, located on the interior as shown. During the bottling process, once element 2 and element 3 are securely interfit, the bottle or reservoir formed would be filled with wine. At that point cap 58 would be screwed onto element 3 with the third set of threads 56 mating with the fourth set of threads 60 forming an air and fluid tight seal. It is to be noted that once the bottle 10 is filled, cap 58 is sealed.

FIGS. 1-5 show the construction of the wine bottle10 at the bottling plant and FIG. 11 shows a possible packaging. FIG. 1 has been discussed above and basically lays out the components and ancillary structure located thereon. Referring now specifically to FIG. 2, the first step in the construction of the bottle 10 is screwing element 2 about element 3. This is done by mating the first set of threads 36 into the second set of threads 48 and turning until sealed. It is to be understood that additional devices or structures may be incorporated into this mating arrangement in order to facilitate an air and fluid tight seal. Once element 2 is affixed securely to element 3, an interior chamber 65 is formed with a single aperture 52.

Referring now specifically to FIG. 3, the next step in the construction of the bottle 10 is placing element 1 into the combination of element 2 and element 3. The stem 14 is received in the parabolic opening 30 and the lip portion 20 snap fits atop top element 32 of element 2.

Referring now to FIG. 4, the bottle 10 is shown in an orientation which places the cap 58 and the aperture 52 on top. It is at this junction where the interior chamber 65 is filled with wine. Once filled to an appropriate level, certainly above the midpoint (MP), the bottle 10 has the cap 58 placed securely thereon. This is accomplished by mating the third set of threads 56 with the fourth set of threads 60 and screwing the cap on. Again, it is to be understood that additional devices or structures may be incorporated into this mating arrangement in order to facilitate an air and fluid tight seal.

FIG. 5 shows bottle 10 in its completed form. It can clearly be seen the inter-relationship between element 1, element 2, element 3 and element 4. The interior chamber 65 is shown filled with wine to a level indicated at 70. This level 70 in no way indicates the desired level, it is for illustrative purposes only. Although the bottle is basically designed to serve a single wine serving, the serving size may vary with type of wine, with the meal that the wine is served with, cultural factors and manufacturing limitations. One of the main embodiments of the invention would be use of such a single serving convertible wine bottle to wine glass on an airline. Referring now specifically to FIG. 11, a four pack 80 of convertible bottles 10 are shown, ready for sale and consumption.

FIGS. 6-10 will show the conversion of the wine bottle 10 to a wine glass. This conversion will most likely take place by the consumer, although a flight attendant, waitress or waiter, bartender or partner may actually perform the conversion prior to being handed to the consumer. The conversion is easily performed, so that anyone can easily perform the steps. The first step is removing element 1 from element 2. This is done by grasping the base 12 and unsnapping the lip portion 20 from the top portion 32 of element 2.

The second step is shown in FIG. 7. Hollow aperture 16 is aligned with cap 58. Hollow aperture 16 has been chosen to be sized so that it frictionally fits atop cap 58 in a secure fashion. The hollow aperture 16 may also be known as a recess. It is to be understood that additional devices or structures may be incorporated into this mating arrangement in order to facilitate a tight seal. Such an arrangement may include threads. FIG. 8 shows the stem 14 and base 12 of element 1 mated with element 4. It can be seen that interior chamber 65 with the wine therein is oriented in the proper direction to be consumed.

FIGS. 9 and 10 shows the removal of the element 2 from element 3, essentially opening the wine bottle 10 and leaving the wine bottle converted into a wine glass. The second set of threads 48 remain on the exterior side 46 of the generally cylindrical sidewall 38. This may help the user grasp the glass. In addition, the second set of threads are down low enough on the exterior side 46 of the cylindrical sidewall 38 to prevent one from becoming engaged with it while drinking from the glass.

Turning to FIGS. 12-14, a second embodiment of a bottle which is convertible into a drinking glass is shown. This bottle 100 is identical to the bottle described above with respect to FIGS. 1-11, except that the third element further comprises a lip 102 and element 2 and element 3 are modified to accommodate the addition of the lip. Accordingly, like reference numerals in this second embodiment refer to like elements in FIGS. 1-11 and the description above is equally applicable to the second embodiment.

The lip 102 extends radially outward from cylindrical sidewall 38 at the circular opening 37 at the top of element 3. When element 2 is screwed tightly onto element 3, the lip 102 seals tightly against the interior side 26 of the bottom of element 2. The lip 102 provides a seal between element 2 and element 3, in addition to the seal provided by the engagement of the threads 36 and 48. To accommodate the lip 102, the diameter of the interior side 26 of the cylindrical wall 22 of element 2 must be increased, also increasing the diameter of the threads 36 on the interior side 26. In order to mate with the threads 36, the cylindrical sidewall 38 of element 3 in the area of the threads 48 are thickened to form a band 104 so that the threads 48 will mate with the threads 36 in interior side 26 of element 2. The band 104 also makes the cylindrical sidewall 38 of element 3 stronger and more rigid in the area of the threads 48. Therefore, the seal provided by the threads 36 and 48 can withstand greater forces caused by squeezing the bottle 100 or other handling of the bottle 100.

Referring now to FIGS. 15-18, a third embodiment of a bottle which is convertible into a drinking glass is shown. This bottle 200 is very similar to the bottles 10 and 100 described above with respect to FIGS. 1-14, except that the connection between element 2 and element 3 is provided by threads disposed on the interior side 44 of the sidewall 38 and mating threads on the exterior side of the centrally disposed portion or depression of element 2. Accordingly, like reference numerals in this third embodiment refer to like elements in FIGS. 1-14 and the descriptions above are equally applicable to this third embodiment.

As shown in FIGS. 15-18, element 3 has threads 202 located on the interior side 44 of the sidewall 38. The threads 202 may be located any desired distance down from the lip 35, so long as the exterior side 206 of the centrally disposed portion 28 is long enough so that the threads 204 can mate with the threads 202. Similar to the band 104 described above with respect to the bottle 100, the cylindrical sidewall 38 in the area of the threads 202 may be thickened to form a band (not shown in FIGS. 15-18).

Element 2 is modified from the configuration shown and described for bottles 10 and 100 so that element 2 will sealingly mate with the modified element 3 of bottle 200. First, the centrally disposed portion 28 of element 2 is cylindrical instead of parabolic as in bottles 10 and 100. Threads 204 are located on the exterior side 206 of the centrally disposed portion 28. The threads 204 sealingly mate with the threads 202 on element 3.

The bottle 200 is filled and assembled into a filled bottle 200 as shown in FIG. 16 the same as described above for bottles 10 and 100. Furthermore, the procedure for converting the bottle 200 into a wine glass as shown in FIGS. 17 and 18 is also the same procedure as described above for bottles 10 and 100.

The present invention also includes several innovative methods of fabricating element 3 utilizing a preform and a blow-molding process. With reference to FIGS. 19-22, a first method for fabricating element 3 will be described. FIG. 19 shows a preform 302 comprising a tubular piece 304. The tubular piece 304 has a smaller diameter than the finished diameter of the sidewall 38 of element 3. The preform also has the neck 50 having the open end 52 and threads 56. The threads 56 may be formed on the preform 302 as shown or may alternatively be formed during the blow-molding process. The preform has a closed bottom 310. The preform is preferably produced by injection molding for plastic parts, or other suitable method considering the type of raw material. A blow-molding mold tool (not shown) is provided which has substantially the shape of the final form of element 3. To form element 3, the preform 302 is placed in the mold tool on a blow-molding machine (not shown). The mold tool clamps onto the neck 50 of the preform 302. The preform 302 is then blow-molded by injecting pressurized gas into the preform 302 thereby producing the blow-molded preform 312 shown in FIG. 20. The threads 48 on the sidewall 38 of element 3 are formed during the blow-molding process. In the case of fabricating element 3 for bottle 200, the threads 202 should be should be included on the preform 302 because it will be difficult to form threads 202 on the interior side 44 of the sidewall 38 by blow-molding. FIG. 21 depicts the final step in the fabrication process which is to trim the bottom surface 314 to create the opening 37. The result is the final fabricated element 3 as shown in FIG. 22.

Another method of fabricating element 3 will now be described with reference to FIGS. 23-26. The preform 320 shown in FIG. 23 comprises a portion of the cylindrical sidewall 38 of element 3 and the threads 48 (or threads 202 if producing element 3 of bottle 200) in the form of the final element 3. The preform 320 tapers down to a narrower tubular bottom portion 322 having a closed end 324. As with the preform 302, the preform 320 may be produced by injection molding or other suitable method depending on the raw material. A blow-molding mold tool (not shown) is provided which has substantially the shape of the final form of element 3. To form element 3, the preform 320 is placed in the mold tool on a blow-molding machine (not shown). The mold tool clamps onto the portion of the sidewall 38. The preform 320 is then blow-molded by injecting pressurized gas into the preform 320 thereby producing the blow-molded preform 326 shown in FIG. 24. The threads 56 on the neck 50 of element 3 are formed during the blow-molding process. The final step in the fabrication process is trimming the closed end 324 as depicted in FIG. 25 to create the opening 52. The result is the final fabricated element 3 as shown in FIG. 26.

Again, it is to be understood that wine is just one of the beverages which may be utilized with the instant invention. Wine coolers, other low alcohol content mixed style drinks and other beverages may be employed with the convertible bottle.

It is apparent from the above that the present invention accomplishes all of the objectives set forth by providing a single serving wine bottle which is convertible to a wine glass.

With respect to the above description, it should be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to those skilled in the art, and therefore, all relationships equivalent to those illustrated in the drawings and described in the specification are intended to be encompassed only by the scope of appended claims.
